The MAX815KCPA: This is not a surplus or last-time-buy part.
Package and compliance detail
Delivered in Bulk (tube or tray) — not tape-and-reel. For pick-and-place assembly, verify feeder compatibility or plan for manual loading. The package is the standard DIP footprint for this class of supervisory IC. RoHS non-compliant. The part contains lead (Pb) above the exemption threshold. BOM lines destined for EU markets or RoHS-mandated assemblies require an exemption waiver or a leaded-process qualification.
What the supervisory IC does in the system
The MAX815KCPA is a microprocessor supervisory circuit — it monitors a single supply rail and asserts a reset output during power-up, power-down, and brownout conditions. In a typical embedded system it sits between the power rail and the MCU reset pin, holding the processor in reset until the supply is stable and within tolerance. Classified under Power Management (PMIC / Gate Driver), it integrates the voltage reference, comparator, and reset timer in one DIP package. No additional external timing components are needed for basic operation.
